In order to effectively suppress the vibration of motorized spindle caused by unbalance fault, realize online dynamic balance control of motorized spindle unit. A self-balancing motorized spindle with dynamic balancing device is designed and the finite element analysis of self-balancing motorized spindle is carried out. The static analysis is carried out, and the static deformation diagram of spindle is obtained after constraint and load are applied. Then modal analysis and harmonic response analysis are carried out, and the first six natural frequencies, mode shapes and displacement frequency curves of spindle are obtained. The results show that: The deformation of motorized spindle is small and rigidity of spindle meets design requirements: Within the working speed range, the spindle will not resonate and work stably and reliably. The rationality and reliability of structure design of self-balancing motorized spindle are verified.
